Application is loading faster than Shopify iframe

Hello

During the first launch a React application is rendered and displayed for a few seconds with the error 'Failed to execute ‘postMessage’ on ‘DOMWindow’, but then the app stops displaying at the Shopify iframe.

As I understood, it happens when an application is loading faster than Shopify iframe…

I have not come up with an idea how to fix it, so could you help me with a solution
